by the cocking lever 39, a sear (see TI! 2,

- 3,13 andl-l) drops in front of a shoulder 46 on the firingfpin. This s'ea'r has an oil-set ari'n 4:7 whiehlies Within a slot 18in the bolt cave bearing 5O ,;.at the front end of the slot 48. V Anotherfflpin extends downwardly a on one side oftlief breech bolt plugrfrouilarni by a spiral spi'ing located within a recess 47. Arm 51 Ihas a fat-e52.which engaged SedrQiAs'the firing.pin is drawn back hollow plunger the breech-bolt plug. The sear is held to its sjeat by the breech-bolt proper, which illcloses the top, of the breech-bolt plug.

' b'eaw-comzecltgr mul trigge'r.,'lhe trigger is'niounted within the trigger guard 3 and cxteii ds at its upper end to a seams below the barrel. The triggerisadaptedj'for' sliding nioveinentionathe seat 56"and has I pivoted to its front end at 57 a trigger-andsear connector which has a portion 58 work iiig iiia slot 59 to one side of shoulders T and 8 on the frame, so that if the trigger-is I I pulled orslid to the rear, and the breech-bolt latter to firing position. :To holdor'lock the connector in this position, until the trig ger released and thereby prevent double fir1ng, I provide the following'ineans: The

connector 58 has a housing extension (52 which overhangsthe forward part'of trigger 55,

thetriggerbeing cut-or recessedat 63 to re-, c.

ceive the housing 62 and t0 perinit the connectorf-t o depi'essedlentirely' within the plane of the trigger. lVhenthe trigger 55 is drawn back to actuate the sear, a latch or plunger 64 has its beveled end 65"brought up against a vertical Wall orface 66 on the franie A and as the plunger 1s being dei ressed a spring 67, which at one end abuts against the plunger or} latch 64, is 0111- pressed. the connector reaches the end of its movement, the plunger. inoves rearward under the action of'its spring 67 and the-connector inits depressed position. The connector stays n this position until the triggerlis released, and as it IS impossible for, one to release the trigger-before the breech-bolt has returned to its orig nalor firing position, owing to the great rapidity at whi'ch the autoniatic opening and closing offithelbreech takes place, it follows that double firing cannot occi'ir. Upon the. re lease of the trigger, the coil'spring 69 causes the trigger 55 to slide or, moveforward on its seat' 56. As the trigger moves forward, the'plunger 64 is withdrawn from recess 68 and the sprin 67Which also acts upon a %0 also carried by housing 62, is permitted to expand and force the hollow plunger 70'to ride upwardly onthe inclined Wall 71 of the recess63,1thus olevati-iig the rear end of" the connector'into a position; that it can eugage the-sear when "thetrigger is again pulled. Of course, on

entersf a recess'68 in said wallg th'us locking,

the downward movement of the connector the plunger also moves to compress spring 67. To limit the outward movement of the plunger or latch 64, said latch carries a projection 72 which engages a lug 72 on one side of the connector portion 58.

Grip.The grip 1, before mentioned, as stated, has a magazine chamber 2, the side walls of which are partially formed of plates 73 which may be of hard rubber, stamped metal or any other suitable elastic material. These plates are slid onto the grip and are held by means of overhanging tracks or guides 74 which lead from the rear of the grip. When the plates are in proper positions on the grip, lugs 7 5 thereon snap into recesses'76 on the grip and hold the plates in position. To remove the plates, ones fingers are introduced into the magazine opening through the bottom of the grip, and pressure is applied to the plates at those portions adjacent the lugs 75. The plates are then slidto the rear. At the front edges of the plates, the grip is provided with vertical grooves 77 into which project fins 78 on the plates, the interlock between the parts preventing the plates working or having play on the grip. j

Magazine born-The magazine box is formed from astrip of metal into a body 7 9 of rectan lar cross section, the lowerend of the body eing closed by a plate 80. The plate has its en s provided with inwardly turned portions or flanges 81 which: are adapted to receive the pair of outwardly turned flanges 82 on the end. of the magazine body, the plate beingconnected to the body by a sliding'movementgiTo prevent the plate sliding off the body, two bosses 83 are struck or pressed u from the latefto engage the inner side wa ls of the b0 y.

The magazine box contains a follower 84 pressed u wardly by a spiral spring 85"; to-

hold the ox within the magaz ne chamber 2, there is provided a lever or latch 93 pivoted intermediate of its ends at 93" in a vertical slot- 94 in the lower front.-,portion of the grip, the lower end of theleverbeing provided with a nose 93* adapted. to enter an opening 2 in the lower end of. the magazine and the upper end 'of the lever lying within a notch 94 in the grip. The latch is normally held in looking position by acoil, spring 95 which lies within an open1ng.,95"

1n the lever and projects from opposite sides of the latter. The projecting portions of the sprin fit within two grooves 94* in opposite wals of the slot 94, the outer end of i the spring seating against the endwalls of the grooves. By posltioning the Iatchatthe lower end of the gri two results arelobtained; first, the latch is covered bythe hand in firin and thus accidental operatiomof.

the late is prevented, and secondly, it is thus as near as possible to the center of osrearwardly under the action ofthe firing,

the follower engages a shoulder 86 on a bolt lock 86. This bolt lock 86 is fulc'rumed in the sidewall of the gri by means of a rounded offset 87 integra with the lock, bored to provide a thin rear wall, havin said wall divided to render it yielding, an

projecting into a recess 88 in the wall of the grip, where it is held by theoverlapping plate 73. As the bolt lock is swung on its pivot,a projection 89 on the bolt lock is swung upwardly and when it reaches its up per position, the projection 89 enters a notch 90 in the breeclrbolt extension and holds the breech-bolt 0 en until the said breech bolt is releaset To release the breech-bolt,, an extension 91 on the bolt lock is depressed. This extension or finger piece extends from the look through an openmg' 92 in the frame to a point to one side of the trigger 53.

trap swioel.-Strap swivels heretofore employed have been so mounted asto be in the way when the pistol isnsedl To obviate this disadvantage the rear lower portion of the grip is bifurcated and the arm 97 of the swivel is fitted in the bifurcation. The bifurcation extends entirely throu h the rear wall of magazine opening 2 so t at the swivel may be swun into the magazine opening, the rear-.wja ing spaced from the box wall so that there is formed a pocket in which thelswivel may lie when thebox is fitted in place as shown inFig.3 f

Embodiment shown in Fig.31.--Another embodiment of the lost motion connection between the striker or firin pin. and the exosed rear of the cockin ever is shown in ig. 31. In this embo iment the cooking lever is formed of two (parts, one portion 39 being pivoted .interme iate its ends at 40, rolling on the inclined surface 45 at its lower end and pivotally connected at itsupper end ofthe opening beat35" with the rearend of the firing pin 31,

and the other or exposed rear portlon bein in the form ofa hood 39 ivoted at 40, an having its upper front e ge ada ted to engage the breech-bolt plug a. noted that any blows on the rear exposed portion will be transmitted to the plug, and not tothe firing in and that therefore the firing pin may 1e against a cartridge in thebarrel without danger.
